Laparoscopic repeat sleeve gastrectomy versus duodenal switch after isolated sleeve gastrectomy for obesity

The results of the present study have shown that laparoscopic re-SG is feasible but carries the risk of fistula development, which is difficult to treat. Laparoscopic DS was also shown to be feasible at a cost of not negligible complications, which are easier to manage than with re-SG. The efficacy seemed greater after DS than after re-SG.
